URGENT – CNN poll: Bernie Sanders surges to join Biden atop Democratic presidential pack

(CNN) — Vermont Sen. Bernie Sanders has improved his standing in the national Democratic race for president, joining former Vice President Joe Biden in a two-person top tier above the rest of the field, according to a new CNN poll conducted by SSRS. The poll marks the first time Biden has not held a solo lead in CNN’s national polling on the race. Overall, 27% of registered voters who are Democrats or Democratic-leaning independents back Sanders, while 24% favor Biden. The margin between the two is within the poll’s margin of sampling error, meaning there is no clear leader in this poll. Both, however, are significantly ahead of the rest of the field, including Massachusetts Sen. Elizabeth Warren at 14% and former South Bend, Indiana, Mayor Pete Buttigieg at 11%. Former New York Mayor Michael Bloomberg lands at 5% in the poll, while Minnesota Sen. Amy Klobuchar and businessman Andrew Yang each hold 4% support. Businessman Tom Steyer has 2%. No other candidate reaches 1% support.
